Hair below the waist?

OK. This is embarrassing. I'm a brunette girl and I have noticed down my crack, tops of my thighs/buttocks and near the back of my vaginal entrance is fairly hairy. When I am ready to have sex I don't want this to be a problem or a turn off when a guy goes down on me or we do it doggy style or he grabs my bare arse. Is this normal and should I do anything about it?
